Application filed February 9, 1921. Serial No. 443,667.

.ful Improvement in Bottle Stoppers, of

which the following is a specification, reference being had therein'to the accompanying drawings. v

My present invention has'for its object a simpleand very cheap bottle stopper 'which can be used in connection with bottles having the ordinary rim or head aboutthe neck and intended to be permanently sealed with crowns. The bottle stopper embodying my invention is intended for repeated use and particularly with highly charged waters,

soft drinks and the like, and can be made very much more cheaply than any bottle stopper capable of repeated use. The extreme cheapness ofthe stop ers embodying my invention makes it possi le to use them not only to replace crowns and for home botfling-purposes and the like, but also as an original closure for bottles which are likely to be opened and closed repeatedly.

. The bottle Stopper embodying m invention comprises only two'parts of w ieh one 15 a simple inexpensive metal stampln and the other is of soft rubber. It inclu es no' moving parts and contains no parts which are likely to wear or to be injured by repeated use and, therefore, forms a durable structure capable of continuous use for a lon time. y

T e invention will be fully understood 7 from the following description when taken in connection with the accompanying drawings, and the novelfeatures thereof will be ointed out and clearly defined in the claims at the. close of this s ecification.

In the drawings, ig. 1 is a side elevation of a bottle stopper embodying my invention.

V Fig. 2 is atopplan view of the bottle stopper shown in Fig. 1. V

- .Fi 3 is a, side elevation of the rubber mem er or plug. 7 c

Fi 4 is a side elevation of the metal mem er.

Referring now to the drawings, the stopper comprisestwo parts, the metal member or clasp, see 11 in igure 4, and the rubber member or plug,-see-12 in Figure 3. The

' clasp comprises asingle pieceof sheet metal of considerablecharacter and thickness died out and shapedlas shown in Figures 1, 2 tad v that the pressure exerted by the clasp 11 will compress the disk portion 9 of the plug 12 between the end face of the neck of the bottle'and the disk of the clasp. The plug also includes a portion h which enters the neck of the bottle and which tends to expand sidewise under the pressure of the as contained in .the contents of, the bottle; t ereby assisting inmaking a ti'ghtclosure. The plug 12 is also provided with ahead we connected with the body thereof by the neck 0. This head m is of a greater diameter'than the hole 7) in the clasp, but the compressibility of the rubber makes it compressible to force the head through the hole in the clasp, and afterward the head e 'pands into the position shown in Figure This construct-ion is such that while it is relatively easy to as semble the parts as described, it is almost impossible to separate them after theyhave clasp 11, although to all appearances sub- ,stantially rigid, hasa slight amount of resiliency which, with the resiliency of the rubber, tends to hold the parts securely in place on the neck of the bottle. It will also I be understood that the rounded portions f *ojf'the clasp engage the inclined under surface of the header rim of the neck of the bottle, but do not contact with the neck at its smallest diameter and therefore the re;-

tends to hold the stopper more firmly in lace on the neck of the bottle and does not have any tendency to work loose or spring off. i

What I claim is 1. A bottle stopper comprisinge. sheet metal plate having amiddle body portion with a holejtherethrough for engagement with a rubber plug, and having downwardly siliency of the rubber and of the clasp itself treat bent spring fingers integral with said body portion for engaging with the neck of a bottle, in combination with a rubber plug having a lower stopper within the mouth of t e bottle, a eripheral flange portion on the upper sid of said stopper portion, a neck surmounting said flange portion. which fits the hole in the plate, said neck being surmounted by a head of larger diameter than the neck, the head, flange and neck forminga peripheral groove around the plug, the head being compressible topermit passage of the head through the. o ening in the plate, the plate and the plug being held in engagement with each other by the neck, head and flange of the plug.

2. A bottle stopper comprising two integral members, one of said members consistin of a sheet metal late havin a middle bo y portion with a ole theret rough forengagement with a rubber plug, and having rtion adapted to fit imao downwardly bent sprin fingers integral within the mouth of a bottle, a peripheral flange portion on the upper side of said stopper portion, a neck surmountin said flange portion which fits the hole m the late, said neck being surmounted by a ead of larger diameter than the neck, the

head, flange and neck forming a peripheral groove around the lug, the head being compressible to permit passage of the headthrough the openin in the plate for assembling the two mem rs and being resilient .so that when the parts are assembled the said head and flange will hold the two members'in assembled arran ement. In testimony whereof afiix my signature.
